Title: Method for detecting ceiling part of car body to be washed
Inventor: IGARI AKIRA
IPC: B60S3/04
Filed: 1992-09-16
Abstract: PURPOSE:To correctly detect the ceiling part position of a vehicle by storing the preceding car height value as fixed data when a difference between the current car height value and the preceding car height value is less than a designated value, and judging the fixed data as the leading end data of a ceiling part of a car body when the condition where the difference is less than a designated value continues. CONSTITUTION:When a car height value (h) amounts to 1100mm or more above the bonnet part, the preceding data (h1) and the current car height value (h) are compared with each other every scanning is performed. If the increase in the car height value (h) is less than 25mm, the car height value at this time is taken as fixed data. When the above condition continues for scanning ten times, the car height value of fixed data is recognized as the car height value of the leading end Q point of the ceiling part 1C. Thus, as the increase in the car height value (h) is gentle, the leading end Q point of the ceiling part 1C can be detected correctly even if the distance from the upper end of the front window part 1B to the ceiling part 1C is long. Accordingly, the distance between a top nozzle 5, the direction of which is turned, taking the Q point as a starting point and the vehicle is expanded so as to solve the problem that drying is insufficient.

Title: Line sequential signal discriminating circuit in reproducing circuit for signal recorded by color difference line sequential system
Inventor: SUZUKI SHIGEO
IPC: H04N9/86
Filed: 1985-11-01
Abstract: PURPOSE:To reduce a discriminating error by delaying a synchronizing signal separated from a luminance signal by a prescribed time, removing noise from a read line sequential signal to amplify and discriminating respective color difference signals by using both the signals. CONSTITUTION:In the line sequential signal (a) in which the noise is removed by an LPF 60, an R-Y signal and a B-Y signal different in level from each other appear alternately, a signal (b) is outputted by a positive-phase amplifier 62, and a signal (h) is outputted by an inversion amplifier 64. A monostable multivibrator 66 responds to a rise of a synchronizing signal (d) separated from the luminance signal, that is, generates a short pulse (e) with the delay from this synchronizing signal. Switches 68, 72 are closed only when the pulse (e) is present, from a comparator 70, a pulse (g) corresponding in time to a start of the R-Y signal and from a comparator 74, a pulse (j) corresponding in time to a start of the signal B-Y. In this manner, even when a central frequency of an FM modulated wave of the R-Y signal and the B-Y signal is stored with a slight deviation, both the signals can be effectively discriminated.

Title: Helical traveling-wave tube
Inventor: TAKAHASHI MASAAKI
IPC: H01J23/26
Filed: 1988-09-29
Abstract: PURPOSE:To improve the heat radiation from a helix by increasing the width of a wedge-shaped cross section at the portion extended from the helix output end of a helix supporting dielectric bar. CONSTITUTION:A helix supporting dielectric bar 2 has high heat conductivity and is made of a ceramic material with a relatively small dielectric constant and has a wedge-shaped cross section. The extended portion 4 from the output end of the helix 1 of the dielectric bar 2 is made remarkably larger in width than other portions. The contact area of the dielectric bar 2 with an envelope 3 can be increased at the extended portion 4 to the collector side, thus the heat generated by the helix 1 can be released in a large quantity to the outside through this portion. This extended portion 4 is in no contact with the helix 1, thereby the high-frequency effect on a helix circuit is small.
